Description
Technical field
The utility model belongs to machinery equipment field, and in particular to interior high pressure after high-pressure molding formed product in a kind of completion
The composable mold of instantaneous punching and follow-up flange before discharge.
Background technique
In the prior art, the hole to in-flanges is processed on interior high-pressure molding pipe fitting, it could not also be while punching
Carry out flange.It needs first to complete punching with a set of punching die, then carries out flange with the independent device to hole of a set of flanging die.Not only need
Two procedures are wanted, and for inside pipe fitting unlike there is interior high pressure when punching, turn-up process usually will appear collapsing of the edges when flange,
Flange low precision, quality are difficult to control.Especially to needing to carry out flange to multiple and different hole on same molded part, will make into
The manufacturing process of type part is complicated, and the manufacturing time period is long, and production efficiency is low.
Utility model content
The purpose of the utility model is to provide a kind of interior high-pressure molding part punching and the composable molds on hole flanging side, including being used for
High-pressure molding part, with punching and hole flanging side is completed in one stroke, is overcoming high-pressure molding part in the prior art with pierce punch
On the inside flanging process in the hole gone out existing for aforementioned deficiency.
The composable mold of the utility model includes: pierce punch, the flange sleeve covered on pierce punch, covers in flange set
Sleeve return spring on cylinder, is assemblied in die insert upper bush pilot hole port at the die insert for having flange sleeve pilot hole
Flange sleeve lock tag；
The pierce punch includes: the cutting edge bar of front end and is greater than the tail of cutting edge bar with the diameter that cutting edge bar is mutually connected
The joining place of bar, cutting edge bar and foot piece forms shoulder, and the angle between shoulder plane and punch axis is identical on die insert
Angle between flange sleeve lock tag and flange sleeve assembly axially bored line, pierce punch are mounted on punching by the clamp of foot piece end
In head fixing seat, formed punch fixing seat is mounted on its connector between oil cylinder；
The flange sleeve moves engagement sleeves on pierce punch, front end of the flange sleeve towards the cutting edge end of pierce punch
For flange extrusion head, there is larger-diameter section at the rear portion of flange sleeve, and larger-diameter section forms support spring towards extrusion head side
Shoulder anchor ring, the diameter of the enlarged diameter section on flange sleeve, greater than the diameter of pierce punch foot piece, the end of flange sleeve rear end
Angle between face and flange sleeve axis, the flange sleeve lock tag and flange sleeve being identical on die insert assemble axially bored line
Between angle, after the circular bead surface of the end face of flange sleeve rear end and pierce punch coincide, front end exposed length is not less than interior height
The drift termination of molded part wall thickness；
Flange sleeve pilot hole on the die insert is to move two sections cooperated with the front and back ends of flange sleeve to differ
The through-hole of diameter, the circular bead surface that two waney through-holes in die insert are formed are that face is held on spring top；
The sleeve loading end for locking piece and being assemblied in die insert upper overturning sleeve pilot hole, locking on piece has and turns over
Sleeve pilot hole concentric pierce punch tail end in side penetrates hole, and the diameter for penetrating hole is less than the rear end diameter of flange sleeve.
The sleeve return spring is compression spring, and the spring one end top covered on flange sleeve is held in flange sleeve
On shoulder anchor ring, other end top is held on the shoulder anchor ring that not isometrical inner hole is formed in insert,
The axial position relationship of insert, formed punch, flange sleeve are as follows: the flange of pierce punch cutting edge end and flange sleeve squeezes
End extends to the die cavity of internal high pressure forming die, concordant with the inner surface of mold, and flange sleeve rear end face is being locked by spring pressure holding
On tag, the breech face of shoulder and flange sleeve on formed punch has not less than at a distance from interior high-pressure molding product wall thickness.
The working principle (process) of the utility model is: in interior high-voltage product in molding moment, oil cylinder pushing pierce punch
Mobile, the shoulder section of pierce punch initially enters in the hole for locking piece, pierce punch punch forming part, in interior high-pressure molding product
Upper pore-forming.Formed punch completes the shoulder surface of punching stroke (usually molded part wall thickness) pierce punch and flange sleeve rear end face is touched
And oil cylinder overcomes the resistance of spring to push flange sleeve mobile, flange sleeve rear end face, which is left, locks piece, the impact extrusion of flange sleeve
The hole that formed punch is gone out at end squeezes flange, until oil cylinder reaches range, entire hole is by the side shape along flange sleeve at this time
Shape translates into straight flange.After completing flange, oil cylinder stroke is reversed, and pierce punch is pulled back to initial position, and flange sleeve is in spring
Lower return is acted on, flange sleeve rear end face closes and locking on piece, flange sleeve stop.Pierce punch and reprint sleeve, which wait, to be entered
Next working cycles.
The good effect of the utility model is: the composable mold of given punching and hole flanging, can be in the wink after punching
When complete hole flange, carry out the flange in hole in the case where molded part has higher interior pressure condition.According to testing inspection, complete at
The punching of type part, hole flanging technique moment, 70% or more pressure is still able to maintain in molded part, this pressure is as product
Inside support avoids and occurs obviously collapsing at molded part punching.Completion punching before interior high-pressure molding release and go out hole
Flange eliminates previous independent flanging process step.Simplify process, shorten the manufacturing cycle of product, reduce manpower,
Equipment investment reduces cost of goods manufactured, improves the quality of product.
